Speccation of Letters Patent.

Application filed August 4, 1914. Serial No. 854,928.

To all whom it may concern: Y

Be it known that we, PETER GRABLER and FRED H. KELsEY, citizens of theUnited States, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have 1nvented new and useful Improvements in Valves, ofwhich the following is a specification.

This invention relates to a device to be attached to an explosive engineof the type employed in driving automobiles, motor boats, and the like,for controlling or varying the air supply to the manifold of the engine.

One of the objects of the invention is to provide means for controllingor varying the supply of air to the manifold, and to vary thetemperature of the air in accordance with the demands of the engine,whereby a maximum efficiency of the engine 1s secured, and the engine isat 4the same time economically operated.

A further object is to provide means whereby kerosene, or the like, maybe in! troduced into the cylinder of the engine while the latter isrunning, for the purpose of cleaning off carbon deposit in the cylinder.

A further object is to provide means convenient to the driver, for theready control and manipulation of the device.

The invention will be hereinafter fully Set forth and particularlypointed out in the claims. f

In the accompanying drawing: Figure 1 is a view of a portion of anautomobile, with our invention applied thereto, parts being shown insection. Fig. 2 is an enlarged perspective view of thel control devicedetached. Fig. 3 is a longitudinal sec.

tional view. Fig. 4 is a cross sectional view. Fig. 5 is a detail viewof the valve operating member.

Referring to the drawing, 10 designates an automobile body, shownconventionally, 11 the engine. and 12 the manifold, of the engine, allof which may be of any usual or preferred construction. Secured to thedashboard 13 of the automobile is a valve casing 14 provided with acylindrical chamber 15 closed by end caps 16, one of which is providedwith an opening 17. The caps are interchangeable and may be secured tothe casing in any preferred manner. As

shown in the drawing, the ends of the caslng are threaded internally,and the caps are correspondingly threaded, and provided with squaredportions 18 to be engaged by a wrench. The casing 14 is provided withtwo inlet openings 19, 20, located at each end, respectively, andleading to the said openlngs are pipes `21, 22, respectively. Leadingoutwardly from the chamber 15 are two outlet ports which communicatewith a common outlet chamber 23 having a dis-v charge opening 24 whichis connected by a pipe 25 with the manifold 12. Within the valve chamber15 is a slide valve 26, prefer-l ably cylindrioal in form andcorresponding in diameter to the diameter of the chamber.

Said valve is approximately a little longer than half the length of thevalve chamber so thatl when the valve is at either extreme of itsmovement it will close one inlet opening and one outlet port, and whenin its intermediate position it will close both outlet ports, leavingthe inlet openings uncovered. The operating rod for the valve extendsthrough the opening 17, and is provided at its other end with anoperating button 30. The operating rod 27 is also passed through aiexible conduit 31, one end of which is secured within the opening 17,the other lend being secured in the lower end of a guide sleeve 32carried by arms 33 secured to the steering column 34 in any suitablemanner. The rod 27 extends through the sleeve 32 and is secured to thesleeve-like extension of the button 30. A springV catch 35 is sei curedto the guide sleeve 32, said catch havf ing a lip to engage said button30 ora groove 36 in the cylindrical portion of said button, so as tolock the valve in either extreme of its movement. It will be noted thatthe inlet pipe 22 has its inlet end 28 wrapped around the exhaust 29 ofthe engine. The casing 14 is provided with a transverse boss 40 locatedopposite the discharge opening 24 and communicating with the outletchamber 23. Connected vwith said boss by a pipe 41 is a priming cup 42,controlled by a valve 43.

During the operation of the engine it is sometimes desirable to supplyairV to the manifold of the engine, in addition to that which passesthrough the carbureter, and the efficiency of the engine at these times,depends upon whether the auxiliary air that is admitted, is hot or cold.By moving the valve 26 so as to cover the inlet opening 20, the adjacentoutlet port is also covered, whereupon the suction of the engine drawscold air through pipe 21 into the chamber 15 and thence into the outletchamber 23, and finally through the discharge port 2d to the manifold12. Should heated air be desirable, the valve is shifted to coveropenyprime the engine, the valve 26 is moved to its intermediateposition to cover the outlet ports, and the desired quantity ofhydrocarbon is placed in cup 42. Then the valve 4:3 isopeiied thehydrocarbon passes through-v pipe 41 into .the outletl chamber 23, andfrom thence to the manifold. In the same manner kerosene may beintroduced to the engine cylinder, without interrupting the operation oftheengine, for the purpose of cleaning off carbon deposit.

Frointhe foregoing it will be seen that our improved auxiliary airdevice is simple in construction, and is .capable of supplying airat thedesired temperature, toconform to the requirements of the engine,thereby insuring economical and eiicient operation of the latter. Itwill also be noted that the device is readily controlled.

Having thus explained the nature of our invention and described anoperative manner of .constructing and using the same, althoughwithoutattempting to set forthv all ofthe forms in whichit may be made, or allof the forms of its use, what we claim is 1. i A valve of the characterdescribed comprisinga valve casing having independent, spaced-apartinlet passages y and spacedapart outlet passages, the outlet passagesleading fronithe casing at a point between the inlet., passages,l and aslidable valve mounted to reciprocate longitudinally within said casing.to selectively close all ofsaid passages.

2. ,A valve of the characted described comprising an elongated valvecasing having independent, spaced-apart inlet passages and spaced-apartoutlet passages, the inlet and outlet passages being Varranged inalinement, a delivery pipe for connecting the outlet passages with theengine manifold,

and a slidable valve mounted to reciprocate longitudinally within thecasing to selectively close the inlet and outlet passages.

3. A valve of the character described comprising a valve VcasingVprovided with removable end caps, one of which is provided with anopening, said casing being provided with spaced-apart inlet passages andspacedapart outlet passages, the outlet passages leading from the casingat a point between the inlet passages, a slidable valve mounted 1mounted to reciprocate within said casing toselectively close all .ofVsaid passages, and.
